Thread: Biggest legal tire size for a disco 4

I have just starting running the Hercules Terra Trac II AT2 LT265/65R18 122/119 Load Index tyre.

Hercules Tires

So far only around town use but super quiet, good road holding and NO RUBBING at any height or full lock. Less than $300 each fitted and balanced.

Spare fitted underneath but did need to be deflated. On the website they list them as 801mm (31.54inch) and the speedo is now spot on with GPS speed checking at every speed test so far.

Keen to give them a test in a couple of weeks and give some feedback

They also list a 275 (32.09) and 285 (32.56) in 65 series for 18" wheels on the USA site, suitable for our D5 friends

So if you want to put larger tyres on a D4 don't pick an obscure size, go with a common size even if it means it's not larger for remote travel.

I think this is a really good point often overlooked in the 'bigger is always better' mindset.

I was just talking to a tyre dealer and hes said 265/65/17 are much more common than 265/70/17, he only carries the 65's.

He also said the 65 are a common size from factory for many models, but the 70 are an aftermarket size, thus not as common.
